nYEGLAss-MOUTING.

Specification of Letters Patent.

Application filed October 4, 1907.

A Patented June 15, 1909.

Serial No. 395,900.

To all whom it may conce-rn:

Be it known that l, CARL i lxooLD, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State olf Wisconsin, have invented new and useful lmprovements in Eyeglass-llountings, of which the following is a specification.

My invention relates to improvements in eye glass mo untings.

The objects of my invention are to provide for increased elasticity in the bridge with reference to movements in a horizontal plane and relatively increased resistance to torsional movon'ients or to movement in a vertical plane as copinared with the ordinary mountings heretofore used, regard being had for considerations oi weight, space, andto the projection ot tbe bridge, the arch of the latter boing brought in close to the intersecting angles of the planes of the glasses.

ln the following description, reference is had to the accompanying drawings, in which,

Figure .1 is an elevation of a pair oi' glasses embodying my invention as seen from the inner side. 2 isl a detail view of one of the mountings showing the inner face of one of the stud boxes. l1 ig. 3 is a view of the samereversed in' position and showing the stud box in section.

Like parts are ident-ined by tbe same reference characters throughout the several views.

The stud posts A are secured to the glasses B by clamps C in the usual manner. The bridge D is coiled near each end in a substantially vertical coil d and the end portion ot' the bridge piece at the bottoni of the coil is provided with a horizontal forward extension d and provided' with a vertically extending extremity 2'which is clamped in the stud box E. A staple il hasone arm f also' clamped in the stud box E and tlie other arm f ot' the staple extends downwardly into the coil d, whereby a winding movement of the coil around tlie staple is permitted but vertical or torsional movements are resisted. The staple serves as a vertical reinforcing member foi' the coil. It is possible to dispense with the staple although its use is preferred for the Areason above stated.

The nose pieces are suspended from yokes G, each of which is clamped in one of the fstud boxes, from which it extends downwardly, inwardly and upwardly on the inner side ol the bridge to a point above the level of the bridge where the nose piece H is se cured by moans ot a rivet r which also serves to secure a bearing member l in position. T he .nose piece H and yoke G may be formed integrally as shown, the rivet serving to prevent tliem froln spreading. Each of the nose pieces extends downwardly from the point of connection 7i. and is provided with an openended longitudinally extending slot fj at its lower end. The lower end of the nose piece is therefore forked, leaving each arm of tbe fork free to adjust itself to the nostrils ol the user. The yoke G and nose piece H may be formed integrally if desired. K is the clamping set screw of the stud box. Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

1. ln an eye glass mounting, a bridge member having near each end a vertically extending depending spiral coil located back of the stud box 'and having end portions extending orwardly and upwardly from the base of the coil and adapted to be'clamped to the stud posts.

2.111 an eye glass mounting, a bridge member having near each end a vertically extending spiral coil and having end portions extending forwardly and upwardly from the base of the coil and adapted to be clamped to the stud posts and a vertical reinforce for each coil extending into the saine from the adjacent stud box.

' 3. In an eye glass mounting, a bridge member liavino near each end a vertically extending spira coil and liaving end portions extending outwardly and upwardly from the base of the coil and adapted to be clamped to the stud posts, clamping stud boxes engaging the extremitiesol the bridge member, and staples clamped in said stud boxes and provided with arms extending into the coils.

ln testimony whereof l affix my signature in the presence of two witnesses.
